Problems solved by technology

However, if the catheter tip is improperly positioned during insertion, or if the catheter tip migrates out of position after insertion, various risks arise, including a fluid infusion that causes pain or injury to the patient, complications due to increased thrombosis rates, delays in therapy, catheter malfunction and additional costs.
However, since PICCs are commonly inserted into a vein in the arm and advanced through the venous system to reach the superior vena cava, the PICC line tip may be inadvertently positioned in a non-target area, such as the internal jugular or subclavian vein.
Further, even if a PICC is property inserted, the catheter tip could later shift out of position if for example the patient coughs violently, moves a lot, or experiences severe vomiting.

Abstract

A catheter assembly includes an elongated member having an ultrasonic beacon disposed adjacent to a distal end portion of the elongated member, a power supply releasably attachable adjacent to the proximal end of the elongated member, and a catheter. The distal end portion of the elongated member with the ultrasonic transmitter is inserted into an anatomical structure of the human body, and the ultrasonic transmitter is powered by the power supply. Using conventional medical ultrasonography equipment, a technician is able to observe and / or track on a display an image of the internal structure of the human body and an image such as an illuminated bright spot representing the energized ultrasonic beacon. After locating the elongated member, the power supply is removed, and the catheter is slid onto the elongated member to locate the catheter tip. Thereafter, the elongated member is removed.

Description

FIELD OF THE INVENTION[0001]The present invention relates generally to positioning a catheter tip such as within a human body. More specifically, the invention relates to methods, assemblies, and devices for positioning a catheter tip using an ultrasonic imaging system.BACKGROUND OF THE INVENTION[0002]Medical professionals commonly use catheters for gaining prolonged access to an area within the body. Once the catheter tip is positioned at the target location, treatments such as antibiotics, chemotherapy, pain medicine, and nutrition can be administered. However, if the catheter tip is improperly positioned during insertion, or if the catheter tip migrates out of position after insertion, various risks arise, including a fluid infusion that causes pain or injury to the patient, complications due to increased thrombosis rates, delays in therapy, catheter malfunction and additional costs.[0003]The general standard for proper catheter insertion depends on the type of catheter and the t...
